Abstract |
: |
Cochineal and weld natural extracts are used for eco-friendly simultaneous dyeing and finishing of silk and wool fabrics to produce functional UV protective fabrics at different dye concentrations (1 or 5 gm/l) for cochineal and (10 or 20gm/l) for weld, dyeing is performed for the two extracts by the traditional pre-mordanting method to produce attractive brilliant red and yellow shades. The dyeing procedure is carried out at pH 4 for both fabrics at a liquor ratio 1:40. The dyeing is started at 40oC and raised to 80oC in 30 minutes then continued for one hour. Finally, soaped using 2 gm/L (Triton X- 100) at 50oC for 30 min., then rinsed and air dried. These two natural extracts have a merit of being combined between high dyeing performance and excellent UV protection properties. In addition they achieved high fastness properties. These natural colorants can be used in UV protective clothes, handmade carpets, and colored blankets. |
